Forms Data Controls :: Built A User Control That Displays A Drop Down List Of States?
Mar 17, 2011
I built a user control that displays a drop down list of states. I'm using it, but if I try to put it in a listview control, all I get is the frop down with nothing in it.
As the tree said to the lumberjack, "I'm stumped". I've been doing .net for years, and my brain is in vapor lock...Very simple here.. I have a user control which has a dropdown list, and a button on it. The DDL is databound. When the button is clicked, I want to retrieve the value of the dropdownlist. I check to see if the page is a postback and if not, I bind the DDL.I put my user control on my master page.When the button is clicked, the value of the dropdown is not obtainable. The selectedvalue is empty. I figure this has something to do with the order of the page being regenerated.
I've got a drop down list that I want to populate with items from a SQL Server database, which I did successfully, but I can't figure out how to write an if statement that will clear the drop down list based on a selected index and repopulate it with data from another table. The drop down list is inside an update panel that auto posts back.
Basically I want to allow the user to choose an item, but rather than populate another drop down list control, i just want to repopulate the current one with new data.I'm guessing that if I want to get data from more than one table the code below isn't going to work for me. Could I get the data from all the tables at once and store each table data in its own variable until I need to use it? (Each table will have under 10 items, in 5 tables.)
Here is the code to get the data from the database:[Code]....
I have the following scenario. I have a page that hosts several user controls. The user controls are all surrounded by a single update panel. All user controls have a save button on them. When the save buttons are clicked the page updates the update panel as expected. Some of the user controls contain editable list views. Whenever an action is taken on these list views, the Update Panel is NOT refreshed, but the whole page posts back. How can I get these ListViews to also refresh the Update Panel? I cannot post the code because of NDA. There are no javascript errors on the page reported by either IE8 or Chrome.
I have a user control in a master page with two drop down lists. When the user selects an item out of either ddl, I want to load a specific user control inside an update panel on the content page. I can't figure out how to get the user control to trigger the update panel.
I have a repeater that displays a list of job openings. I now need to modify the repeater and break out the job openings by category.
See below for the existing code for my repeater. I'm not sure how I need to modify my repeater to display the jobs under the appropriate categories.
I've added a new JobsCategory table to the database and added the foreign key relationship between my jobListing table and the jobcategory table.
I've created a new stored procedure to pull the jobs my category:
CREATE PROCEDURE [dbo].[GetJobsByCategory] @categoryId int AS BEGIN SET NOCOUNT ON SELECT j.JobID, j.JobTitle, j.URL, j.City, j.State, j.Country, c.CategoryName FROM ADPJobListing j INNER JOIN ADPJobCategory c ON j.CategoryID = c.CategoryID WHERE j.CategoryID = @categoryId END
In my typed dataset (tableadapter), I'll add a new query to the above stored procedure and finally in my business logic layer, I'll add a new method to call down into my data access layer:
[DataObjectMethod(DataObjectMethodType.Select, false)] public ADP.JobsDataTable GetJobsByCategory(int categoryId) { return this.Adapter.GetJobsByCategory(categoryId); }
How do I need to modify my repeater to display the jobs by category?
I have drop down list box that I would like to show two columns, is this possible? Or can it be done with a list box?The query correctly retrieves all of the table data to be displayed, one colum is an abbreviation, the other a bit longer description.
I have a country table that has a list of countries. However, instead of just displaying the list alphabetical, I need to list the United States first, and then all the other countries in Alphabetical order. My select statement is pretty simple, jsut don't know how to get the US listed first...
when i am using dropdownlistin asp.net when i amselect the value from the list it cannot that the selected value but it can take only the first value of list.
I have a gridview with a drop down list. When I do the update I try to get the value from the drop down list, but I get an error saying that the drop down list control 'ddlType' can't be found.
In this code you can see the select statement that the customers are selected for display to the user. Order by is at least being used to disply in name order. but this example here is one of several similar dropdowns. I would like that if they picked one customer then the next view show should be the same customer
< order by customername " asp:SqlDataSource ID="Customers" runat="server" ConnectionString="<%$ ConnectionStrings:SecurityDB_20101025ConnectionString %>" SelectCommand="SELECT * FROM [Customers] WHERE ([CustomerId] = ISNULL(@CustomerId, '') OR @IsSuperAdmin = 1 ) > [code]...
I have a drop down list bound to a column in a database. If a user logs into the website using the standard login controls, I want the drop down list to automatically select there name from the list. here is the code that doesn't work
[Code]....
The error orrcurs here:

Which intellisense says "Property Access must Assign to it's property or use it's values". Do I have the code all wrong? Also, as a side question, I don't understand why I have to use the TryCast find control option to find every control to use them. Even in the Page_Load if I type in DropDownList1 it says it's not declared.
I'm using vs2008 and add a dropdown list in my page. Default value of this control is "Digital". When I select another value from the list and press a button, next time the page displaying the same value, i.e Digital, not the selected value. I just want to show the selected value on the page.
I added 3 values on DropDownList controls. ID= DropDownList1. If a user selects a value from the DropDownList, I'd like to insert the value on my DB (DB = Test) and in Column (Column = LastName). Below is the code I get when I double click on the DropDownList.
Protected Sub DropDownList1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles DropDownList1.SelectedIndexChanged End Sub
How would I re-code the datagrid below so it displays as a drop down list? The data I want to display in the drop down list is ID="dgvFitters".Also, is it possible to display the data in a datagrid and in a drop down list simultaneously?
I have a ListView that contains a lot of editable items. Every item has some values, like; item name, item price, item size and so forth. I would like to add another editable column which should be a drop down list. This should list which sizes the item is available at, like S, M, L, XL. Some item are only available in S and M, while other items may just have a standard size (meaning none of the above sizes). So for example if you are to add an item called polo shirt and its only available in sizes L and XL then you should be able to do that. And then at the front-end where the users surf the items it should be like that when a users sees this Polo shirt he should be presented with a drop down list where he is only able to select L and XL
I can't figure out how to implement this in the Listview and the database. I have mentioned that I want a drop down list to appear in the back-end, this is not a necessity, anything will do as long as the front-end is showing a drop down list with the choosen sizes.
what the problem is that i want to populate drop down list manually
but the thing is i have 3 drop down lists
in first one user will select table name from where the data of 2nd Drop Down list will come
suppose user selected seo then the sql query would be select project_name from dropdownlist1.selecteditem
and this query will show project_name column of seo table in dropdownlist2
then user will select any project name from dropdownlist2 suppose he select salveo so i want that my text box will get populate with project_id of project_name
suppose the project_id of salveo is 123 then automatically in textbox it will enter 123
